Are you ready to #StartSomething? Canadian Windows Phone devs, start your engines and score killer rewards!

The Mango App Challenge has come and gone. The contest elicited a huge response and many happy, Canadian developers now have the sweet goodness of Mango on the Windows Phones they won as a result of publishing 2 apps to the Windows Phone Marketplace. Now we up the ante. Get ready to #StartSomething by joining the Developer Movement and build Windows Phone apps to win seriously awesome prizes. Fire up Visual Studio or XNA Game Studio and get started!

So, what exactly is the Developer Movement? Well, it’s a contest like the Mango App Challenge was, but it’s actually even more than that. You can win a wide variety great prizes (not just phones this time) by creating and publishing new Windows Phone apps to the Marketplace, for sure, but what we’re hoping is that you join us to start a revolution in the mobile space.

Who is this contest for? In a nutshell, if you are Canadian, it’s for you. Whether or not you’ve built a mobile app/game before, built an app/game for a competitive platform like Android, iOS, Blackberry, etc., built a Windows Phone app before or not, this is a great offer for you. For details on eligibility, I would check out the Terms and Conditions.

How do I get started? Easy. Go to the Developer Movement site and click on the Get Started button. If you are one of the first 200 to sign up and you don’t already have a Marketplace publisher subscription, you’ll get signed up to the Marketplace for one year for free. Just for signing up. (Don’t forget, if you are a student enrolled in an school that is participating in Microsoft’s Dreamspark programme you get a free membership already). Once you’ve done that, go to the Developer Toolkit page and download the SDK, check out our learning resources and watch some of the video tutorials we provide!

What do I get if I publish apps and games and submit them to the contest? The prizing is tiered depending on the number of apps/games you publish. The prizing is detailed on the Rewards page of the Developer Movement site. Hint: the prizes are really, really good.

I signed up for the developer movement and it sent me the necessary information to create the app hub account. The instructions indicate that I should use the same publisher name that I used on the developer movement forms when signing up in app hub but when I try that it keeps saying invalid account. Am I doing anything wrong?

One of the things that sometimes trip people up when registering to the App Hub is the publisher email address being the same as the developer email address. Try using a different email for the developer email address (keep the publisher email as the one you used for the Developer Movement sign-up process).

I'm following the instruction "When you sign up for App Hub to complete the registration process, make sure you use the same publisher name that you used to register for the Developer Movement, shown here"
